OT: Ever carry a 9 volt battery in your pocket?

An alkaline or heavy duty type battery will probably just get warm. But if you use a lithium rechargeable battery, your pants may catch on fire if a coin or keyring gets across it.

An alkaline or heavy duty type battery will probably just get warm.

Crucially for 9 volt types, when one of the six cells goes flat the remaining 5 reverse charge it causing the explosion.

But if you use a lithium rechargeable battery, your pants may catch on fire if a coin or keyring gets across it.

The current levels are much higher and results way more spectacular than with alkaline etc.

I managed to get some AA nicad cells and my key chain make a circuit in my pocket. At first I though maybe I got bit since I was hiking, but I dug in the pocket and determined it was the batteries.

Removing your brain was a good idea, but clearly it didn't affect your ability to post trolls or crap. Try removing other things, like the plug for your computer next time.

Removing your mother from my pants was an even better idea, D*****ad.

Done that. If it gets shorted by coins or something, it will get quite warm.

Why was she wearing your pants?

Don't forget never to carry batteries in the same pocket as your steel wool

He was wearing her dress & heels, of course.

Or slightly corroded bullets.

Or even spare blasting caps

About 45 years ago I had a battery something like this one (

At age 12-13, I was experimenting with inductance, using the motor from my Erector Set, clicking on a 6V lantern battery then dumping into a flashbulb (Press 25)... melted it over my finger :-( :-( :-(

(Still have the scar. Damn! That really hurt!)

Ooh, I'm impressed.

A cop in Trenton Ohio learned the hard way not to carry a spare battery for his police radio in the same pocket with spare bullets. He had done it before, and occasionally had a dead spare battery. The last time he did it, one of the bullets had enough surface resistance at the base of the brass casing, and went off in his pants pocket. That was in the early '70s, and I'll bet he's never tried it again.

I was about the same age when I put 5 or 6 D cells in a paper towel tube and put the voltage across the motor out of a record player. At the time I couldn't understand why I got a JOLT everytime I disconected the wire from the battery. Mike

I recall seeing a video of a policeman who accidentally pulled the pin on his flashbang while it was still in his trouser pocket (for some reason or other). Probably got what we used to call a "deadleg" as kids.

My mother used to wrap her spare hearing aid battery in aluminum foil

- I don't recall if she noticed it getting warm, but she wondered why her "new" spare battery was always dead... (I saw her unwrapping the battery one day, and cured her of the habit.)
